According to the left-hand rule, how do you position your fingers around the coil?

The left-hand rule is a mnemonic used in physics to determine the direction of force, magnetic field, or current in electromagnetic situations. When applying the left-hand rule to understand the behavior of a coil in a magnetic field, the correct approach is to position your fingers in the direction of electron flow, which is equivalent to the conventional current direction (from the positive terminal to the negative terminal).

By positioning your fingers in the direction of current flow, your thumb will then point in the direction of the magnetic field created by that current. In this context, the left-hand rule helps visualize the relationship between the electrical currents flowing through the coil and the magnetic forces that result from them.

Understanding this interaction is crucial for analyzing electric motors and generating electromotive forces in coils. Therefore, aligning your fingers with the direction of electron flow correctly applies the left-hand rule in practical electrical applications.
